Equations — Writano Docs

Type one LaTeX equation and Writano both typesets it and plots it — with sliders, parametric curves, and single-parameter animation.

The Equations tab turns a formula into a figure. You write a single LaTeX expression; Writano renders it and plots it from the same source, so the curve can never disagree with the equation printed above it.

One source, rendered and plotted

Enter an equation in LaTeX. It is parsed to a mathematical model and compiled once into a fast plotting function, then drawn over your chosen range. Because the rendered formula and the plotted curve come from the same expression, they always match.

y = a \, \exp\!\left(-\frac{(x - \mu)^2}{2\sigma^2}\right)

Sliders and parameters

Free symbols in the equation become sliders, so you can vary a parameter and watch the curve respond in real time. Only $\pi$ and $e$ are treated as constants — every other letter is a parameter you control. Parametric curves are supported, and a single parameter can be animated to sweep through a range.

Export the plot

Export the equation plot as a PDF figure or insert it into your paper. The equation is stored with the figure, so reopening it brings back the formula, the ranges, and the slider values for further tweaking.

Tip: Use sliders while you explore, then fix the parameters to the values you want before exporting the final figure.
